| Program Setting Function and PID Parameters Switching |
| Segment PID selection |
PID-parameter numbers being used can be selected on a segment basis. Zone PID selection: PID parameter sets are selected depending on the value of the applied PV input. Either the reference point method (reference point; a setpoint for switching between PID parameter sets) or the reference deviation method is used for the switching. |
